Abstract

Cette invention porte sur une optimisation de débit de multidiffusion, en particulier sur un procédé de commande d'un codeur (1) dans un système de communication (3) comprenant une pluralité de récepteurs (2). Le procédé comprend la division des récepteurs (2) en au moins une cellule, et l'association de chaque cellule à un débit spécifique qui peut être utilisé pour transmettre des signaux à un récepteur (2). Selon le procédé de l'invention, des incertitudes dans des estimations de conditions du système de communications (3) sont prises en compte par modélisation des conditions, telle que la distorsion moyenne perçue par les récepteurs (2), en tant que résultat d'une variable stochastique, pour ainsi tenir compte d'incertitudes dans les estimations des conditions du système de communication (3). L'invention porte également sur un codeur associé au procédé.
